Bow With Adjustable Handle

ABSTRACT

A versatile hunting bow with a circular rotatable handle mounted on a circular frame of the riser of the bow. The riser is skeletonized and has an asymmetrical shape. The archers can rotate and adjust the orientation of the handle to their natural wrist position. The outer wall of the circular handle has a series of parallel thread cuts that match with the thread cuts on the inner wall of the circular frame of the riser. Two limbs are connected and secured to the riser through limb bolts. When limb bolts are tightened, the geometry of the riser and the arrangement of the limbs create tensions that slightly distort the shape of the riser. The distortion prevents the thread cuts from moving along each other. Thus, the handle is no longer able to rotate when the limb bolts are tightened and the handle is locked.

FIELD OF THE INVENTION

This invention relates to archery bows and compound bows. In particular,this invention relates to a versatile compound bows with adjustable androtatable handle that allows archers to hold the bows with their mostcomfortable and natural wrist position.

BACKGROUND

Accuracy in archery is often materially affected by the stance of thearcher, the way the archer grips the bow, and the unbalanced forcegenerated in releasing the string. Several problems are commonlyassociated with archery. These problems include bow torqueing, fatigueof the archer, insufficient strength and insufficient forearm clearance.

Bow torqueing is a common problem associated with an archer's poor handposition when gripping the handle of the bow. Hand torque occurs whenthe archer exerts pressure on the bow's riser at the handle andunintentionally twists the bow when the archer releases the string. Thistwist turns the proper position and creates mis-alignment of the allowaxis to the handle, which subsequently causes the arrow to travel in anunintended direction. This could also result in the arrow fishtailing.The accuracy of the archer is significantly affected by the hand torqueand mis-alignment. The torqueing problem is usually remedied by trainingthe archer to adopt proper hand position. However, in situations such asbow hunting, archers sometimes find themselves shooting from unusual orinconvenient locations, thus preventing the archer from gripping the bowin a proper position.

The alignment and the position of the bow when the archer aims are alsoimportant to achieving accuracy. The bow should be vertical when thearcher aims and shoots. To align the bow vertically, archers are oftenrequired to turn their wrist and elbow away from their most natural andcomfortable position. This could easily tire many archers, causing poorform and accuracy.

Forearm clearance refers to the space between the archer's forearm ofthe arm holding the bow and the arrow. Insufficient forearm clearancecan result in a part of the arrow, such as the fletch, contacting theforearm or the clothing of the archer when the arrow is released. Thiscan alter the normal travel path of the arrow, causing the arrow to missthe target. Normally, the archer's bow arm, his line of sight, and thesight aim should form a straight line and be aligned with the arrow'sline of travel. Such proper form inevitably reduces forearm clearancebecause the bow arm has to be straightened and be positioned adjacent tothe arrow. For most of the common stances in archery, the archers oftenfind themselves in a dilemma in maintaining the proper stance whilemaximizing forearm clearance.

SUMMARY

In view of the foregoing, the present invention is directed to aversatile hunting bow with a special riser that comprises a circularrotatable handle which allows the archers to adjust the handleorientation to their most nature wrist position. The present inventionis also directed to a hunting bow with a circular rotatable handle,which can be locked through tightening the limb bolts that connect thelimbs and the riser of the bow.

In some embodiments of the present invention, the versatile bowcomprises a riser, an upper limb and a lower limb secured to the riserthrough limb bolts, a string or a set of strings connected to the farends of the upper limb and the lower limb, a sight and an arrow restmounted on the riser and located at the approximate center of the bow,and two stabilizers. The riser is made of skeletonized metal alloys suchas magnesium alloy. The riser comprises mainly four regions—a circularframe that is ring shaped, a lower arm connected to the lower side ofthe outer circumference of the circular frame, an upper arm connected tothe upper side of the outer circumference of the circular frame, and acircular rotatable handle mounted on the circular frame. The handle canrotate circularly along the inner circumference of the circular frame.

In some embodiments of the present invention, the riser has anasymmetrical shape. The circular frame is located in the lower part ofthe riser. The upper arm is connected to the circular frame at aposition slightly right of the middle of the riser. The location of thecircular frame and the upper arm allows the arrow rest to be placedright at the center of the entire bow so that the arrow's line of travelcan be aligned more accurately to the orientation of bow. A turn existsin the middle of the upper arm so that the limb pockets at the upper armand the lower arm can align with each other.

In some embodiments of the present invention, the inner wall of thecircular frame contains a series of parallel thread cuts. Moreover, thecircular handle comprises a handgrip along its diameter and a circularwall along its circumference. On the outer circumference wall of thehandle, it also contains a series of parallel thread cuts. The depth anddimension of the thread cuts should match with those of the thread cutson the inner wall of the circular frame. Thus, when the handle is put inthe circular frame, the handle is mounted on the riser through matchingthe thread cuts. Since both thread cuts are parallel, the handle canfreely rotate planarly along the inner circumference of the circularframe without the chance of coming off from the riser.

In some preferred embodiments of the present invention, the bowcomprises a locking mechanism that allows archers to lock the handlewithout installing or using any additional structural component. Theriser has a special geometry in which the upper arm and the lower armelevate away from the position of the circular frame so that thecircular frame is located at a position closer to the string. When thelimb bolts that secure the limbs to the riser are tightened, the stringof the bow creates a tension that pulls the upper limb and the lowerlimb toward each other. As a consequence, the limbs create a force thatpulls the elevated upper arm and lower arm of the riser slightly towardthe position of the circular frame. This slightly distorts the shape ofthe riser, especially the shape of the circular frame. Since the threadcuts on the inner wall of the circular frame and those on the outer wallof the handle match with each other, they are sensitive to slight changein shape. As a result of the distortion, the parallel thread cuts can nolonger move along each other smoothly. Thus, the distortion in the shapeof the riser prevent the handle from further rotating. This locks theorientation of the handle. However, when the limb bolts are loosened,the string and the limbs no longer create any tension. The riser returnsto its natural shape. Now the thread cuts can move along each other.This allows the archers to turn the handle when the limbs of the bow arenot tightened.

DETAILED DESCRIPTION OF EMBODIMENTS

The following description is made for the purpose of illustrating thegeneral principles of the invention and should not be taken in alimiting sense. The scope of the invention is best determined byreference to the appended claims.

The invention now will be described more fully hereinafter withreference to the accompanying drawings, in which embodiments of theinvention are shown. This invention may, however, be embodied in manydifferent forms and should not be construed as limited to theembodiments set forth herein. Rather, these embodiments are provided sothat this disclosure will be thorough and complete, and will fullyconvey the scope of the invention to those skilled in the art.

Exemplary embodiments of the present invention are described herein withreference to idealized embodiments of the present invention. As such,variations from the shapes of the illustrations as a result, forexample, of manufacturing techniques and/or tolerances, are to beexpected. Thus, embodiments of the present invention should not beconstrued as limited to the particular shapes of regions illustratedherein but are to include deviations in shapes that result, for example,from manufacturing.

FIG. 1A is a perspective view of a versatile bow 10 in accordance withan embodiment of the present invention. The versatile bow 10 comprises ariser 20, an upper limb 42, an lower limb 46, two cams or pulleys 90 and92, a system of strings 94, two stabilizers 82 and 84, an arrow rest 86,and a sight 80. The upper limb 42 and the lower limb 46 are connectedand secured to opposing ends of the riser 20 by the limb bolts 404. Theversatile bow 10 can be dismantled by unscrewing the limb bolts 404 anddetaching the upper limb 42 and the lower limb 46 from the riser 20. Anupper cam 90, preferably a compound cam, rotatably engages with one endof the upper limb 42. A lower cam 92 also rotatably engages with thelower limb 46 in the same or similar way of the upper limb 46. A systemof strings 94, extending between and connecting at the ends of the upperlimb 42 and the lower limb 46, tangentially touches the track in thecams 90 and 92. The riser 20, the limbs 42 and 46, the cams 90 and 92,and the system of strings 94 are the key working components of theversatile bow 10.

Different accessories can be added to the versatile bow 10 to increaseits functionality and accuracy. As shown in FIG. 1A, an upper stabilizer82 and a lower stabilizer 84 are inserted to the riser 20. Thestabilizers 82 and 84 are installed to dampen vibration and steadyarcher's bow arm when the archer is aiming. They also reduce torqueingwhen the archer releases the strings 94. An arrow rest 86 with a restbracket is mounted to the riser 20 at a position right above thecircular frame of the riser 20. Preferably the arrow rest 86 should belocated at the center of the riser 20 so that the arrow head can berested on the center of the versatile bow 10 and the arrow's line oftravel can be aligned more accurately to the orientation of theversatile bow 10. A sight 80 is located right above the arrow rest 86and is mounted, statically or pivotally, on the riser 20 to assist thearcher's targeting. To enhance the accuracy of targeting, the sight 80should be located adjacent to the arrow rest 86 so that the axis of thebow sight is parallel to the arrow's line of travel.

It will be appreciated that different accessories can be connected tothe riser 20 through the apertures and the skeleton structure of theriser 20. The apertures 38 and 40 and the structural elements 30 and 32are best shown in FIG. 2A and FIG. 2B. For example, stabilizers withdifferent shapes and orientations can be inserted to various apertureson the riser 20 at different locations. Also, the archer can choose thepreferred brand and model of sight 80. The versatile bow 10 can be usedfor shooting without any accessories mounted on the riser 20.

The upper limb 42 and the lower limb 46 are made of slightly flexiblematerials compared to the riser 20. The materials of the limbs 42 and 46can be wood or plastic. The limbs 42 and 46 are relatively flexible sothat when the archer pulls the strings 94, the limbs will temporarilybend inward towards each other. This provides part of the recoilingforce to propel the arrow when the archer releases the strings 94. Theriser 20 remains rigid to provide mechanical strength to the bow whenthe strings are drawn. It will be appreciated that the limbs 42 and 46are replaceable. For example, they can be aftermarket products so longas the limbs can be connected and secured to the riser 20 through thelimb bolts 404. The length of the limbs 42 and 46 can vary, depending onthe preference of the archer and the desired strength of the versatilebow 10.

FIG. 1B has dotted lines to define a key direction and a key surface ofthe bow 10. The dotted line that passes through the arrow rest 86represents the line of travel 98 of the arrow. The dotted rectanglerepresents a plane 99 that is substantially perpendicular to the line oftravel 98 of the arrow. The plane on which the circular frame 22 flatlysits is substantially parallel to the plane 99. The plane on which thehandle 21 rotates circumferentially is also substantially parallel tothe plane 99. The phrases “rotate planarly” and “rotatecircumferentially” should refer to the direction of rotation of anobject on any plane that is substantially parallel to the plane 99.

The riser 20 is the middle and the most rigid part and the largestcomponent of the versatile bow 10. Preferably, it is made of materialsthat are strong, rigid and light. It can be fabricated from magnesiumalloy, aluminum and titanium alloys, fiber-reinforced polymers, carboncomposites, or glass-loaded polymers. A variety of manufacturingtechniques may be employed to fabricate the riser. In the cases of metalalloys, machining or casting may be used. In the cases of carboncomposites or other polymers, molding with a bladder can be used toachieve the desired shape of the riser 20.

Referring now to FIGS. 2A, 2B, and 3, FIG. 2A is a front view of a riser20 of a versatile bow 10 showing a circular rotatable handle 21 inaccordance with an embodiment of the present invention. FIG. 2B is aside view of the riser 20 shown in FIG. 2A. FIG. 3 is the perspectiveview of the riser 20 shown in FIG. 1A. FIG. 1A shows several majorregions of the riser 20, including a lower end 24, a lower arm 25, acircular frame 22, an upper arm 27 with a turn 28 that bend the upperarm 27, and an upper end 26. The lower limb pocket 36 is located at thelower end 24, and the upper limb pocket 34 is located at the upper end26. The circular frame 22 is the part on which the circular rotatinghandle 21 is mounted or installed. The lower arm 25 is the riser's lowerelongated region that is in between the lower limb pocket 36 and thecircular frame 22. The upper arm 27 is the riser's upper elongatedregion that is in between the upper limb pocket 34 and the circularframe. The shape and dimension of the lower arm 25 and the upper arm 27are best illustrated in FIG. 3. The riser 20 also contains two apertures38 and 40. These apertures are provided for stabilizers 82 and 84 orother accessories to be installed (FIG. 1A).

The riser 20 has an asymmetrical shape. For the purpose of illustration,a dash line is added to represent the middle axis of the riser 20 inFIG. 2A. The circular frame 22 is located in the lower part of the riser20. Under the view of FIG. 2A, the portion of upper arm 27 before theturn 28 that is connected to the circular frame 22 is located slightlyright of the middle axis of the riser 20. The location of the circularframe 22 and the upper arm 27 allows the arrow rest 86 (shown in FIG.2C) to be placed right at the center of the bow 10 so that the arrow'sline of travel can be aligned more accurately to the orientation of theversatile bow 10. The space between the middle vertical axis and theupper arm 27 before the turn 28 provides location for the sight 80 andthe arrow rest 86 to be placed so that the sight 80 and the arrow rest86 can be located on the middle vertical axis for more accurate aimingand shooting, as shown in FIG. 2C.

Referring now both to FIG. 2A and FIG. 2C, FIG. 2C shows the front viewof the riser 20 with the upper limb 42 and the lower limb 46 installed.Slots 44 are located at the upper end of the upper limb 42 and the lowerend of the lower limb 46 for the cams 90 and 92 to be inserted. Theupper limb pocket 34 and the lower limb pocket 36 must be aligned sothat when the string 94 and the cams 90 and 92 are installed, the string94 will be vertical and be located at the middle axis shown in FIG. 2A.Thus, the turn 28 is present to bend the upper arm 27 towards the middlevertical axis. The unique asymmetrical shape of riser 20 allows thestring 94, sight 80 and arrow rest 86 all be located at the middle ofbow 10. The alignment of these components allow the arrow to be shotfrom the center of the bow 10 and travel in a direction perpendicular tothe plane shown in FIG. 1B. The archer's line of sight will also bealigned and parallel to the travel direction of the arrow. This enhancesthe accuracy of arrow shooting using the embodiments of the presentinvention.

Referring now specifically to FIGS. 2B and 3, the figures show the sideview and perspective view of the riser 20. In a preferred embodiment ofthe present invention, the riser 20 is skeletonized to reduce the weightof the riser 20 and to provide aesthetic appearance to the riser 20. Theskeletonized riser 20 can also provide structural elements 30 and 32 forbow accessories, such as sight 80 and stabilizers 82 and 86, to bemounted on the riser 20. The exact shape and dimension of the structuralelements 30 and 32 would depend on the design of the bow 10 and theintended accessories to be mounted on the riser 20.

FIG. 3 shows the inner wall of the circular frame 22. The inner wallcontains a series of parallel thread cuts 23. The depth and dimension ofthe thread cuts 23 can be based on the Unified Thread Standard.Preferably, approximately six to eight threads are cut per inch. Otherdensity of the thread cuts 23 may also be used. When the handle 21 isinstalled, the handle 21 can rotate planarly on the plane of thecircular frame 22, which is the surface that is substantiallyperpendicular to the direction of travel of the arrow 98, and be lockedin a manner that will be described in a greater detail below. Therotational direction can also be described as rotating circumferentiallyalong the inner circumference of the circular frame 22 or rotatingconcentrically with the center of the circular frame 22.

Referring now to FIGS. 5A and 5B, FIG. 5A is an isolated front view ofthe circular rotating handle 21 according to an embodiment of thepresent invention. FIG. 5B is the perspective view of the handle 21. Thehandle 21 is a circular structure with a handgrip region 62 along itsdiameter. The handle 21 can be made of any materials that are strong,rigid and light. In a preferred embodiment, the handle 21 is made of thesame material as the riser 20, such as magnesium alloy or aluminum andtitanium alloys. Machining or molding can be used to manufacture thehandle 21. Preferably, the handle 21 should be rigid enough to withstandthe tension from the riser 20 in the locking mechanism that will bedescribed in a greater detail below. The outer diameter of the handle 21should match the inner diameter of the circular frame 22 in the riser sothat the handle 21 can be mounted on the circular frame 22 without thechance of coming off. On the outer circumference wall of the handle 21,it contains a series of parallel thread cuts 64. The depth and dimensionof the thread cuts 64 should match with those of the thread cuts 23 onthe inner wall of the circular frame 22. Thus, when the handle 21 is putin the inner circular space of the circular frame 22, the handle 21 ismounted on riser 20 through the matching of the thread cuts 64 and 23.Since both 64 and 23 are a parallel series of thread cuts, the handle 21can freely rotate along the inner circumference of the circular frame22. The handgrip region 62 can be made of the same materials as the restof the handle 21. It can also made of other soft materials or rigidmaterial covered by soft materials so that the archers can hold the bow10 more comfortably.

Referring to FIG. 6, archers using the versatile bow 10 can rotate thehandle 21 to adjust the orientation of the handgrip region 62. Theadjustable rotating handle 21 allows the wrist of the archers to be atvarious angles to the bow riser 20. The adjustable rotating handle 21allows archers to hold the bow 10 at their most comfortable and naturalwrist position and provides the archers maximum forearm clearance to thestrings. The natural wrist position also allows the archers to draw thestring 94 with maximum power and to shoot more accurately by reducingthe possibility of torqueing. When the archers release the string 94,the archers are less likely to twist the bow because they are grippingthe bow at their most comfortable position.

However, if the handle 21 is freely rotatable during string drawing andreleasing, the orientation of the handle 21 could change slight at themoment the string 94 is released. This will result in the movement ofthe bow 10 and torqueing, thus affecting the accuracy of shooting. Toaddress this issue, in preferred embodiments of the present invention, amechanism is provided to lock the orientation of the handle 21 after thearchers have adjusted the orientation of the handle 21 to their mostcomfortable and natural wrist position. The locking mechanism will bediscussed with greater detail below.

Referring now to FIG. 4, it shows an enlarged prospective view of anupper limb pocket 34 in accordance with an embodiment of the presentinvention. It should be understood that the structure and the componentsof the lower limb pocket 36 are substantially the same as those of theupper limb pocket 34. The upper limb pocket 34 comprises two sidewalls304 and a bottom wall 302 to form an enclosed area for the upper limb 42to be inserted. An aperture 310 is located in the middle of the upperlimb pocket 34 near the bottom wall 302. Referring to FIG. 1A, when theupper limb 42 is inserted into the limb pocket 34, the upper limb 42 issecured by limb bolt 404. The limb bolt 404 is screwed from the topsurface of the upper limb 42 and penetrates through the aperture 310 totighten the upper limb 42. Returning to FIG. 4, in some embodiments ofthe present invention, two additional apertures 308 are present in theside opposing the bottom wall 302. These apertures 308 provideadditional means to secure the upper limb 42 by any type of mountingdevices such as screws or rivets to be inserted through the apertures308.

FIG. 7A shows how the limb bolt 404 secures the limb 42 or 46 in thelimb pocket 34 or 36. When the limb bolt 404 is screwed all the way in,the limb 42 or 46 will be completely tightened in the limb pocket 34 or36. When the limb bolt 404 is loosened, the limb 42 or 46 will still beattached to the riser 20. Yet, the limb 42 or 46 will not be entirelysecured or tightened. Unscrewing the limb bolt 404 entirely allows thearchers to replace the limb 42 or 46.

FIGS. 7A, 7B, and 7C illustrate a convenient mechanism to lock theorientation of the handle 21 in some preferred embodiments of thepresent invention. This mechanism allows archers to lock the handle 21without using or installing any additional structural component. FIG. 7Bshows the side view of the riser 20 when the limb bolts 404 in FIG. 7Ais screwed all the way into the aperture 310. The limbs 42 and 46 arecompletely tightened and the spring 94 is stretched. This createstension on the spring 94 that pulls the limbs 42 and 46 towards eachother. Referring now to the geometry of the riser 20 in this side viewFIG. 7B, the riser 20 has a special shape in which the upper arm 27 andthe lower arm 25 of the riser 20 elevate away from the location of thecircular frame 22. Thus, the circular frame 22 is located closer to thespring 64. When the limbs 42 and 46 and the string 94 are tightened, thestring 94 pulls the limbs 42 and 46 towards each other. This tensionalso pulls the upper arm 27 and the lower arm 25 of the riser 20slightly backward toward the location of the circular frame 22. Thiscreates internal tension in the riser 20. As the circular frame 22 islocated in between the upper arm 27 and the lower arm 25, the tension inthe riser 20 that pulls the upper arm 27 and the lower arm 25 towardsthe location of the circular frame 22 slightly distorts the shape thecircular frame 22. The change in shape of the circular frame 22 isusually hardly noticeable by the naked eye because distortion is slight.But since the dimension and size of the thread cuts 23 and 64 on theouter wall of the handle 21 and on the inner wall of the circular frame22 match, the interaction between these thread cuts are highly sensitiveto slight change in the shape of the circular frame 22. As a result ofthe distortion, the thread cuts 23 and 64 can no longer move along eachother smoothly. Thus, the slight distortion of the circular frame 22 issufficient to prevent the handle 21 from moving. Therefore, when thelimb bolts 404 are tightened, the orientation of the handle 21 is lockedeven though the limb bolts 404 and the handle 21 are not directlyconnected or even interacted with each other. Preferably, the riser 20is made of metal alloys and is skeletonized to slightly increase thedegree of distortion of the circular frame 22 so that the handle 21 islocked more tightly. The unique geometry and arrange of the riser 20provides a convenient locking mechanism to the handle 21 without anyadditional component.

FIG. 7C shows the side view of the riser 20 when the limb bolt 404 inFIG. 7A is loosened. Although the limbs 42 and 46 and the spring 94 arestill attached, these components are loosened and no tension exists inany component of the bow 10. Thus, no tension is created in the riser 20and the circular frame 22 is restored to its original shape. Now thethread cuts 23 and 64 can move along each other. In this arrangement,the handle 21 can freely rotate planarly in the circular frame 22. Thearchers can rotate and adjust the orientation of the handle 21 to theirpreferred position before shooting. The archers can then lock the handle21 by tightening the limb bolts 404. This type of locking mechanism ispreferable for most archers because archers commonly loosen the limbbolts and limbs for better storage. They usually only tightened the limbbolts before the shooting. Therefore, the adjustment of the handle 21can be carried out before shooting and the locking of the handle 21 canbe achieved with any additional steps other than tightening the limbbolts 404 required.

Other locking mechanisms may also be used for the embodiments of thepresent invention. For example, a stopper, such as a clip, a clasp, or abrace, can be installed at one point of the circumference of thecircular frame 22 to connect the circular frame 22 and the handle 21 tohold the handle 21 in position.
